Greetings. Just picked up this 10mm pistol as a specific use backup to a Moss 500 tach shotgun for bear defense in Alaska. I have larger pistols but can't carry them long distances backpacking due to weight. I'm also not confident that I could rapid fire my S & W 629 44 mag in any event. I'm a small guy and that cannon is just a bit too much. I selected the 10mm because it's the biggest that I could both carry and actually hit something with. The 10 doesnt' recoil much at all.
Anyhow, I'm going to put about 750 rounds a year of 180 grain FMJ stuff through it each year practicing. Then during bear defense carry, I'd use Buffalo Bores 220 grain hard cast lead flat nose ammo. I might practice with 50 220 grain bullets per year. I might also put 200 rounds or so of Double Tap 200 grain hard cast flat nose through it a year in practice. I was watching hickock45's youtube video and he seemed to be having some tumbling issues with the 230 grain bullet, so I figured I'd go with the 220.
QUESTION: Will this hotter ammo damage the OEM Glock barrel, affect reliability or risk injury to me?
If so, I'm happy to put an aftermarket barrel in it. I'm wondering if someone could refer me to a good AM barrel, if needed. Reliability is critical for this use, making cost irrelevant.
Thanks for any help. Great forum!
